Title: Add SYSTEM to table and routine types

As viewed through information_schema. Recently proposed and no one objected.

Main motivation is making consuming metadata simpler (e.g. from cli, jdbc). For example, to avoid materialized, but still system, tables at the moment (e.g. information_schema.index_statistics) an extra schema check is needed.
